Bose Condensation of Photons Thermalized via Laser Cooling of Atoms

August 31, 2018
Author(s)
Chiao Wang, Michael Gullans, James V. Porto, William D. Phillips, Jacob Taylor
A Bose-Einstein condensate (BEC) is a quantum phase of matter achieved at low temperatures.Photons, one of the most prominent species of bosons, do not typically condense due to the lackof a particle number-conservation. We recently described a photon

Photon thermalization via laser cooling of atoms

July 19, 2018
Author(s)
Chiao-Hsuan Wang, Michael Gullans, James V. Porto, William D. Phillips, Jacob Taylor
The cooling of atomic motion by scattered light enables a wide variety of technological and scientific explorations. Here we focus on laser cooling from the perspective of the light — specifi- cally, the scattering of light between different optical modes

Efimov States of Strongly Interacting Photons

December 4, 2017
Author(s)
Jacob M. Taylor, Alexey V. Gorshkov, Michael Gullans, D Ruzik, Seth Rittenhouse, J.P. D'Incao, Paul Julienne, S Diehl
We introduce a new system to study Efimov physics based on interacting photons in cold gases of Rydberg atoms. This system has a large anisotropy between the longitudinal mass of the photons, arising from dispersion, and the transverse mass of the photons

Valley blockade in a silicon double quantum dot

November 13, 2017
Author(s)
Justin K. Perron, Michael Gullans, Jacob Taylor, Michael Stewart, Neil M. Zimmerman
Electrical transport in double quantum dots (DQD) is useful for illuminating many interesting aspects of the carrier states in quantum dots. Here we show data comparing bias triangles (i.e., regions of allowed current in DQDs) at positive and negative bias

Threshold Dynamics of a Semiconductor Single Atom Maser

August 31, 2017
Author(s)
Michael Gullans, Jacob M. Taylor, Yinyiu Liu, J. Stehlik, Christopher Eichler, X Mi, T Hartke, Jason Petta
We demonstrate a single-atom maser consisting of a semiconductor double quantum dot (DQD) that is embedded in a high quality factor microwave cavity. A finite bias drives the DQD out of equilibrium resulting in sequential single electron tunneling and

Narrowband Optomechanical Refrigeration of a Chiral Bath

August 7, 2017
Author(s)
Jacob M. Taylor, Kim Seunghwi, Xu Xunnong, Gaurav Bahl
The transport of sound and heat, in the form of phonons, is fundamentally limited by disorder-induced scattering. In electronic and optical settings, introduction of chiral transport - in which carriers have unidirectional propagation - provides robustness

Optical Radiation from Integer Quantum Hall States in Dirac Materials

June 30, 2017
Author(s)
Michael Gullans, Jacob M. Taylor, Mohammad Hafezi
Quantum Hall systems exhibit topologically protected edge states, which can have a macroscopic spatial extent. Such edge states provide a unique opportunity to study a quantum emitter whose size far exceeds the wavelength of emitted light. To better

Optomechanical Quantum Correlations at Room Temperature

June 23, 2017
Author(s)
Thomas P. Purdy, Karen E. Grutter, Kartik A. Srinivasan, Jacob M. Taylor
By shining laser light through a nanomechanical beam, we measure the beam’s thermally driven vibrations and perturb its motion with optical forces at a level dictated by the Heisenberg measurement-disturbance uncertainty relation. Such quantum effects are

Optomechanical Quantum Correlations

May 18, 2017
Author(s)
Thomas P. Purdy, Karen E. Grutter, Kartik A. Srinivasan, Nikolai N. Klimov, Zeeshan Ahmed, Jacob M. Taylor
We present methods to measure optical quantum correlations arising from an optomechanical interaction even when large classical noise sources are present. We demonstrate quantum- backaction-noise-calibrated Brownian motion thermometry as a metrological

Observation of optomechanical buckling phase transitions

March 1, 2017
Author(s)
Jacob M. Taylor, John R. Lawall, Haitan Xu, Utku Kemiktarak, Jingyun Fan, Stephen Ragole
Correlated phases of matter provide long-term stability for systems as diverse as solids, magnets, and potential exotic quantum materials. Mechanical systems, such as relays and buckling transition spring switches can yield similar stability by exploiting

Entangling distant resonant exchange qubits via circuit quantum electrodynamics

November 16, 2016
Author(s)
Jacob M. Taylor, Vanita Srinivasa, Charles Tahan
We investigate a hybrid quantum system consisting of spatially separated resonant exchange qubits, defined in three-electron semiconductor triple quantum dots, that are coupled via a super- conducting transmission line resonator. By analyzing three
